Other than Christmas, my family doesn't really celebrate most holidays, but I do try to get my mom and dad something for Mother's/Father's Day, and a little something for their birthdays. DH's family sends their wishes over the phone, with no gifts involved.
Christmas with both of our families used to be huge events, with a big dinner, pricey gifts for immediate family, and additional gifts for extended family. It was overwhelming, to be honest. How do you choose an appropriate gift for people you only see once a year, and how is an average person supposed to afford all of that? Whew! Thankfully the gift-giving and elaborate dinners have dwindled down over time. I like seeing everybody and catching up, but I also like keeping things simple!
